Passengers from other stricken ship say they have no interest in another cruise

Carnival to pay each passenger $500 in addition to refunds, credits

Federal agencies have joined the engine room fire investigation

Much-needed supplies and a third tugboat are heading across the Gulf of Mexico to try to make the end of the miserable voyage of the Carnival Triumph as comfortable as possible for hungry travelers who have waited in lines for hours for food and other necessities.

Carnival Cruise Lines said Wednesday afternoon it has dispatched another tugboat to help two others tow the disabled and befouled cruise ship to port in Mobile, Alabama, with U.S. Coast Guard escorts on the scene.

The cruise line also said it would compensate passengers $500 each in addition to measures previously announced, including refunds.

Carnival said on its Facebook page that it decided against sending another ship to pick up passengers because towing the ship to port was the safest option.

The Coast Guard delivered equipment to the struggling ship Wednesday afternoon, including a generator and electric cables.

Nerves are frayed on board, where passengers have waited in lines for as long as four hours, said Nick Ware, whose mother is on the ship with her boyfriend. Ware said arguments are breaking out after people at the front of lines grab as many provisions as they can.

"The person in the front of the line is allowed to take however much he wants, so people see the person in front of them taking too much, (and) they start to get concerned they're not going to get any," Ware said.

People at the rear of the line ended up with buns and condiments -- no burgers, he said.

Meanwhile, on shore, Kim McKerreghan stood in the dark at dockside in the Port of Mobile early Wednesday, worried about her 10-year-old daughter and her ex-husband, both passengers on the distressed cruise ship.

Her daughter, Allie Taylor, called her in a panic Sunday after a fire broke out in the Carnival Triumph's engine room.

Automatic sprinklers extinguished the blaze, but the flames paralyzed the ship's propulsion system, leaving it temporarily marooned in the Gulf of Mexico, subject to the whims of wind and sea currents.

"Mommy, it's so scary," McKerreghan said her daughter told her. "I want to come home." McKerreghan fought back tears as she recalled the conversation. "Just come get me," her daughter begged her.

The cell phone signal was bad, and they ended the call, leaving the mother from Lufkin, Texas, feeling helpless. "I wanted to have a meltdown," McKerreghan said. "I'm going to have that moment here," she told CNN's Victor Blackwell at the Alabama port.

Cruise ship limps to port

Ware said he has been told that some of the public restrooms work, meaning that people waiting in those lines can stop using red biohazard bags for waste.

Slow trip home

For most of the day Wednesday, two tugboats dragged the nearly 900-foot, 14-story Triumph at a jogger's pace to the harbor, where the 3,143 passengers and 1,086 crew members on board will get off the vessel on Thursday, the cruise line said.

The convoy was approximately 108 nautical miles (about 124 statute miles) from port around 5 p.m. ET Wednesday, the Coast Guard said. The ship is on track to arrive at the Mobile dock around 4 p.m. ET Thursday, an official briefed on plans for the recovery of the ship said.

The Triumph is expected to navigate the "safety fairway," or the corridor into Mobile Bay, late Wednesday night, bringing it around 10 a.m. Thursday to the point where a pilot from the Port of Mobile will board the ship and guide it to dock, the same official said.

Mobile Infirmary Health Services has offered to set up a triage unit at the port, in case any debarking passengers need medical assistance, Alabama Cruise Terminal General Manager Sheila Gurganus said Tuesday.

Then, after what Gurganus predicted would be "easy access out the door of customs with your luggage," about 200Carnival employeeswill try to take care of its passengers on land.

"We are currently finalizing travel arrangements for guests from Mobile. Carnival Triumph guests were given the option of boarding buses directly to Galveston or Houston, Texas, or to spend the night in a hotel in New Orleans, where they could rest before flying out on private charters the next day. Carnival will cover all travel-related and incidental expenses," the cruise line said.

Carnival said it has reserved and arranged approximately 100 motor coaches, more than 1,500 New Orleans hotel rooms, multiple charter flights from New Orleans to Houston on Friday and transportation from Houston to the Port of Galveston so that guests may retrieve their cars if they drove to the port.

'It's disgusting'

The cruise ship left Galveston for a Caribbean tour last week and was scheduled to arrive back there Monday.

That day, McKerreghan's ex-husband, stranded at sea, phoned to say the sanitary situation had already begun to deteriorate on board the Triumph.

"He said that the conditions have gotten so bad that they're asking them to use the restroom in bags, and they were eating onion sandwiches," McKerreghan said.

The call was the last she has heard from them.

Much of the ship's electrical power went down in the fire, causing widespread malfunctions, including taking out sanitary systems.

Passengers have reported sewage sloshing around in hallways, flooded rooms and trouble getting enough to eat.

"From what I understand, they're walking around in a lot of urine and fecal matter, and the sewers are backing up," McKerreghan said. Her doctor gave her antibiotics to give her daughter as soon as she gets on land. A checkup will follow as soon as possible.

Passenger Jet Hilton from Crawfordsville, Indiana, has relied on her sense of humor to get through the ordeal, her sister Jennifer Stanfield told CNN affiliate WTHR.

Four-thousand people on a stranded ship can't flush, Hilton jokingly messaged Stanfield, venting about the stench on board.

The fire is at least the second problem for the ship since late January, when it had an issue with its propulsion system, according to a notice posted on the website of Carnival senior cruise director John Heald.

And it's not the first fire to disable one of the cruise line's ships.

In 2010, the Carnival cruise ship Splendor lost power after an engine room fire, leaving it drifting off the Pacific coast of Mexico. The USS Ronald Reagan ferried 60,000 pounds of supplies for the ship's passengers and crew as the ship was towed to San Diego.

For Laura Chavez, who was aboard the Splendor, news of the Triumph's debacle brought back unhappy memories. "That's exactly what we experienced," she told CNN. "It's very disappointing to hear that they're experiencing that again."

The Splendor's toilets also overflowed. "Oh, yeah, terrible, bad, bad, bad," she recalled. "We saw it coming through the seams, through the ceilings."

The 52-year-old flight attendant said she and her traveling companion took the cruise line's offer of a free trip, but news about the Triumph has soured them forever on Carnival. "I wouldn't want to go through that again," she said.

Food was in short supply then, too, she said. "At the very end, I was living on a box of Rice Krispies."

Another Splendor passenger said he was astounded that something so similar happened to the Triumph.

"For me, that was my first trip and my last trip" aboard Carnival, said Marquis Horace, a 38-year-old actor in Los Angeles. "The definition of insanity is you keep trying something and expect a different result. It's the same result: the ships keep breaking down. Why would I do that?"

A U.S. Coast Guard marine inspector told CNN that the Triumph passed inspection last year, earning a "certificate of compliance" on May 17.

Damage control

Passengers will get a free flight home, a full refund for their trip and for most expenses on board, as well as a credit for another cruise, Carnival said.

Brent Nutt, whose wife, Bethany, is on the ship, said it's not worth it.

"First of all, we only paid $350 for her to go on this cruise. Her safety and her well-being are worth a whole lot more than $350," he said.

And the free stuff?

"I promise you, none of my family members that are on there will probably ever, ever take another cruise," he said.

The Coast Guard and the National Transportation Safety Board launched an investigation into the cause of the engine room fire. Because the Carnival Triumph is a Bahamian-flagged vessel, the Bahamas Maritime Authority is the primary investigative agency.

McKerreghan drove from Texas with a friend, Mary Poret, whose 12-year-old daughter Rebekah is on board, with Poret's ex-husband.

Poret also received a frightening call from her daughter after the fire and feared they may never see each other again. "I will grab her, hold her in my arms and not want to let go," she said.

After this ill-fated cruise, the Triumph won't host vacationing passengers until at least mid-April. Carnival has canceled a dozen voyages scheduled between February 21 and April 13. That makes a total of 14 scratched trips. The cruise line already had eliminated voyages slated for February 11 and February 16.

In a statement, Carnival vowed that customers who paid for those 14 trips will receive a full refund of their cruise fare, non-refundable transportation costs, pre-paid shore excursions, gratuities, and government fees and taxes. In addition, Carnival said it would offer the inconvenienced travelers a 25% discount on a future three- to five-day Carnival cruise or a 15% discount on a six- to seven-day cruise, while protecting travel agent commissions.
